Abstract

PURPOSE:To pass a truck smoothly by pushing up a triangular columnar-shaped saddle body so as to be projected from a floor face by a spring and normally projecting the saddle body from the floor face while sinking the saddle body from the floor face when wheels such as the truck are passed. CONSTITUTION:When wheels such as a truck are passed, the wheels collide so as to ride on the inclined plane of a triangular columnar-shaped saddle body 1 even when the diameters of the wheels are small while the main body 1 is sunk easily from a floor face 2. Slipping-off from a slot 2a bored to the floor face 2 of the main body 1 is prevented by stopper pieces 1b projected in the cross direction along the base of the main body 1 from both edge sides of the base. Door stop members are mounted on the floor face 2 in the vicinity of both ends of the main body 1, and the lower end section of a door is made to collide. The main body 1, the spring 3 and the door stop members are incorporated into a frame body as required, and installed onto the floor face under a unified state. Accordingly, the impact of the truck passed on a saddle can be reduced, the state of the closing of the door can be held, and part control and the workability of mounting can be improved.

As disclosed in Japanese Patent No. 8687, as shown schematically in FIG. 12, when the wheels R of a trolley such as a wheeled sleeper pass through when protruding from the floor F so that the lower end of the door D contacts. The shape of the wedge K that can be immersed from the floor is a substantially trapezoidal cross section. When the wheel R passes, the smaller the diameter of the wheel R becomes, the more vertical the vertical cross section of the wedge K is. The wheel R abuts on the surface K ′, and it becomes difficult for the skid K to sink from the floor surface F, and the impact increases when the wheel R passes.

In order to stop the door D by the lower end of the door D coming into contact with the wedge K protruding from the floor surface F, the height of the other vertical surface K ″ of the wedge K having the substantially trapezoidal cross section is raised. It is necessary to increase the height H to some extent, and it is difficult to prevent the wheel R of the truck from hitting the vertical plane K ″ and reduce the impact. Furthermore, since the contact surfaces of the skid K and the floor surface F are vertical surfaces, there is a problem that a gap is apt to occur, the hermeticity is poor, and dust enters from the gap.
